The Corgis are a group of dogs who live in Goodsprings. They are a group of assassins who eventually died to the dangers of the wastes, and were soon forgotten throughout the entire Mojave Wasteland.
The story of the Corgi's tells the fall of their assassins group. It takes place around Thanksgiving, called" "A Very Corgi Thanksgiving".
The Corgis were typical assassins, who lived in Goodsprings. Soon though, a man named Dan Enrique came to Goodsprings and questioned the Corgis' whereabouts. When no one gave him answers, he eventually killed Easy Pete. Seeing Pete dead, the Corgis knew that people were after them in order to end their group. They died in many ways, from being shot, to explosions, to STDs. It wasn't long until the Corgi's withered down to 3: Dog 1, Dog 2 and Dog 3.
Knowing they are wanted for assassinations, the town of Goodsprings became worried that they would have the same fate as Easy Pete. For a short period of time, they were able to live with them, but the remaining Corgi's were soon forced out of Goodsprings due to the fact that they were responsible for the town's massive amount of dog shit.
After the 3 dogs had left, they soon died on Thanksgiving Day and withered away due to starvation and no shelter. Afterwards, the town of Goodsprings celebrated Thanksgiving.
As mentioned above, they appear in "A Very Corgi Thanksgiving". They also appear in Al's Fallout New Vegas mod review of "New Vegas Trade Center" where they are Al's companion. However, during the course of the mod, 3 of the dogs turned hostile, along with Steve. Al was then forced to kill Milo, Harrel, and strangely Milo again.
It was revealed that the Corgis were actually alive, as they make a final appearance in New Vegas Montages: Farewell New Vegas, having been captured by the Business Radroaches and the Radios. They are eventually freed by Al and assist him in taking down the Business Radroaches in the bunker before leaving with the rest of Al's secondary companions, heading out into the wasteland while Al promises to save the Mojave.
